Target not working???

[Mark Smith]

Since a stack that is in use is available to all other stacks (it's  
script has been inserted into back), maybe it would be better simply  
for any stack that needs to use the libStack to'register' and  
'deregister' with the libStack, which can then put itself in and out  
of use as necessary.

in a client stack, for example

on openStack
   put the long name of me into myName
   send "libStackregister myName" to stack "/Users/Dave/Desktop/ 
TestLib/Lib.rev"
   pass openStack
end openStack

on closeStack
   put the long name of me into myName
   send "libStackDeregister myName" to stack "/Users/Dave/Desktop/ 
TestLib/Lib.rev"
   pass closeStack
in the libStack

and in the libStack

on libStackRegister tClient
   set the clients of me to the clients of me & cr & tClient
   start using me
end libStackRegister

on libStackDeregister tClient
   put the clients of me into cList
   get lineOffset(tClient,cList)
   if it > 0 then delete line it of cList
   set the clients of me to cList
   if the clients of me is empty then stop using me
end libStackDregister
